 This machine applies large volume fluidized bed can automatically dry,filter,
Product name: Auto batch two time expansionpre-expander 1400
Auto batch multifunctional pre-expander 1400

it is used for multifunctional pre-expanded machine, it can expand particular low density foamed beads,it can make the low and high density eps material beads together.
it applies the PLC and touch screen monitor automatical control system.
ithas the weighing system, feeding material system, temperature control
it keep the density tolerrance within+-2.8%
it has two drying system, it can automatically dry,filter,crush the ball material and transport the foamed material to aging silos.
the closed constant pressure foaming barrel has high heating efficiency, which can save 50% energy compared with the continuous pre-expander

  1. This machine is used for secondary pre-expanded machine,it can expand particular low density foamed beads,it also can be used for first pre-expansion after technical reform.It is a multifunctional pre-expander machine.
  2. This machine applies PLC and touch screen,automatic feeding,electronic weighing,temperature control,material level control to realize automatic production.
  3. Electronic weighing system and material level control system assure the density of the foamed material, which make the bead uniform and keep the density tolerance within±2.8%.
  4. This machine applies automatic material charging system,electronic weighing system and PLC central control system,which realize automatic feeding and weighing,improve production efficiency and reduce labor intensity.
  5. The closed constant pressure foaming barrel has high heating efficiency. It can save more than 50% energy compared to the continuous pre-expander.The foamed beads are uniform,and its aging time is shorter compared to other normal machine.
  6. This machine applies large volume fluidized bed can automatically dry,filter, crush the ball material and transport the foamed material to aging silos.
  7. This machine applies automatic high pressure suction material charging system and automatic high pressure fan facility discharging system,which shorten the materials charging and discharging time,improve the production efficiency.
  8. Most of the main component are of world-famous brand,with reliable performance,stable quality,long service life and low maintenance cost.
  9. The computer has memory function, which can record all information such as brands, specifications, expanding foam techniques and parameters of EPS material manufacturers. When customers want to use the materials that ever been used before just press the touch screen of computer to quickly go back to the original technique.
  10. The electronic weighing system device is assembled on the top of the machine frame,the structure of the machine is compact,it occupies smaller space.
  11. This machine is applicable in plateau oxygen depletion area,the production efficiency of continuous pre-expander machine is quite low under such circumstance.
